'Application April 25, 1938, Serial No. 204,194 Renewed August 7; 1939 2 Claims.

' This invention relates to an improved window holder and seeks, among other objects, to provide a device of this character which, when attached to a window casing, will permit the Window to be raised without interference but which, after the Window has assumed a desired raised position,

will automatically engage a portion of the window for holding it in'the desired raised position.

Another object of the invention is to provide a window holder employinga frame whichwill prevent thefwindow-engaging element from injury, and will guide said element into and out-oi operative position. I

A furtheriob-ject of the invention is to provide a device ofthis character wherein means are provided on the "frame for limiting too great rearward movement of the window-engaging element.

As a still further object, the invention seeksto provide. a window holder which may be positioned on a Window frame in such a manner that the window-engaging element employed may be shifted to a position for locking the window and permitting unauthorized raising thereof.

A still further object of the invention is to provide a window holder which will lac-effective for preventing rattling of a window sash in a window frame.

A further object of the invention is to provide a device of this character which is characterized by utmost simplicity of construction and ease in operation.

Other objects of the invention not specifically mentioned hereinabove willbecome apparent during the courseof the following description.

Our invention is illustrated in the accompanying drawing, wherein 1 Figure l is a vertical sectional view of easing showing in elevation, our improved window holder as it will appear thereon and in locked position against a raised window sash.

Figure 2 is an enlarged side elevation showing the window holder in engagement with a portion of a window sash, the out of engagement position being shown in dotted lines,

Figure 3 is an enlarged perspective view of our improved window holder and showing the norm bination pivot and mounting bolt as it will appear before insertion through the frame, and

Figure 4 is an enlarged side elevation showing our improved device as it will appear when inverted and used as a lock.

Referring now more particularly to the accompanying drawing wherein similar reference numerals will be seen to indicate like parts throughout the various views, the numeral l indicates a window .of the bolt 29.

ear 12 against the face of the element 24, with I consequent clamping of said element, will be pre- 1 in general a window frame having a silli and a side member 3. Slidably mounted in the window frame i are sashes t and 5 which are of any de sired construction andinclude side rails t.

1 In carrying our invention into effect, we em" ploy a frame which is shown in general at l. The frame includes an oblong base plate il'which is adapted-to be fastened to the side member 3 by means of screws 9. and Ill. The frame 7 is formed froin'a single piece of sheet metal'and is reduced and bent at its rear edge to' define a right angularly disposed'rear stop wall ll,.and

said wall l i has formed thereon a reduceddowrwardly inclined ear l2 which liesin parallel spaced relation to the plate 8 and defines a hearthe stop wall H when the device is in inoperative position. In that position, as will "be noted, the wall I5 is disposed in parallel relation to the front edge of the plate 8. The engaging element Hi is provided with a curved rear wall it having an opening i9 therein which is adapted to receive therethrough a bolt 22. As will be clearly under stood'from a scrutiny of Figures 2 and 3 of the drawing, the bolt 29 extends through the bearings 13. through the opening 19, and through an alined opening in the plate 3. The boltis, of course, screwed into the side member 3 of the window casing or frame and said bolt, therefore, serves to mount the device on said casing in the most rigid manner possible. That is to say, the bolt 28 serves a two-fold function in that it pivotally mounts the element 84 between the plate 8 and the ear l2 and, at the same time, said bolt assists in securing the device in a properly installed position on a window casing. The metal employed in the manufacture of the frame 1 is of suitable thickness so that enough strength will be present to resist too great inward movement Therefore, danger of forcing the vented.

Although the operation of the invention as deorder. After the device has been installed on the window casing or frame, and the sash, for example, the sash 4, is raised, the element M will swing slightly to the rear, that is to say, toward the position shown in dotted lines in Figure 2, and will not impede the raising movement of the sash. After the sash has been raised to the desired position, the sash is released and the engaging element M will rock forwardly automatically and will engage the cam face l6 with the side rail 6 of the sash, for effectually holding the sash in the desired position. In order to release the element and permit the sash to slide downwardly toward closed position, it is only necessary to enage the lower end portion of the curved wall 8 of said element and urge the lower end portion of the element inwardly, when the cam surface IE will be rocked away from the rail 6 for freeing the sash.

As shown in Figure 4 of the drawing, it is pos sible to employ our improved window holder for locking the window against raising movement. When the invention is used in this manner, it is mounted on the window frame in inverted position, that is to say, in a position inverted with respect to that in which the device is mounted when being used merely as a holder. The cam surface l6 will be engaged, in locked position, to the lower rail of the sash and will prevent raising thereof. In order to insure proper locking, the element i4 is swung rearwardly, which swinging movement is accomplished by manually engaging the upper end portion, shown at 2|, of said element and shifting said upper end portion in the direction of the arrow. Shifting of the portion 2| in the opposite direction will, of course, release the element and permit raising of the window. The use of this embodiment of the invention is particularly efi'icacious for the reason that the device wil prevent unauthorized raising of the window by burglars or thieves. Moreover, when the device is in locked position, the window will be prevented from rattling. It is thought that further description of our invention is unnecessary.

Having thus described the invention, what i claimed as new is:

1. In a window holder, a frame adapted to be positioned on a side rail of a window and including a mounting plate projected to form a stop wall, said stop wall being projected in overhanging relation to define an ear, said mounting plate having openings to receive fastening devices whereby the window holder may be secured to the side rail, an engaging element carried; by the frame between the ear and the mounting plate and within the confines of the frame when said element is in inoperative position, and means mounting the engaging element in the frame for pivotal movement, said means alsoaiding in securing the device to the side rail, said engaging element; having a straight front wall curved at t one end to define a camming surface engageable with a portion of a window sash for holding said sash in a fixed position and against downward movement, said front wall permitting free raising of the sash, said element having a rib engageable with the stop wall in retracted position, said stop wall limiting too great rearward movement of the slightly inwardly curved lower portion ,cooperating with the straight front wall to define a manually engageable portion, and means for mounting the element on a side of a window sash so that the cam face will be automatically engaged With the side rail for limiting downward movement of the sash, said manually engageable' portion bee ing shiftable for confronting the straight front wall of the element with the sash for freeing said sash.
